Description

圧電素子を用いたタッチパネル構造Touch panel structure using piezoelectric elements
　本発明は、入力箇所に対して振動を出力するタッチパネルに関するものである。 The present invention relates to a touch panel that outputs vibration to an input location.
　現在、タッチパネルに入力する際、使用者に対して体感振動を出力する振動発生装置が付加されたものがあり、基本的な構造としては特開平０４－１３７４１９（以下特許文献１として記載）が出願後、公開されている。 Currently, there is a device with a vibration generating device that outputs bodily sensation vibration to the user when inputting to the touch panel. Japanese Patent Application Laid-Open No. 04-137419 (hereinafter referred to as Patent Document 1) has been filed as a basic structure. It has been released afterwards.
　前記特許文献１記載の構造では、接触等によるタッチパネルへの入力信号を検出する検出回路によってタッチパネルへの入力を検出する制御方法を用いている。この為、駆動時には別途設けた制御回路によってタッチパネルへの入力を確認し、振動源に出力することでタッチパネルを振動させる構造となっている。 In the structure described in Patent Document 1, a control method is used in which an input to the touch panel is detected by a detection circuit that detects an input signal to the touch panel due to contact or the like. For this reason, at the time of driving, the input to the touch panel is confirmed by a separately provided control circuit and output to the vibration source to vibrate the touch panel.
　前記特許文献１記載の方法では、タッチパネルへの加振方法に関して、単に振動アクチュエータを設けたのみの構造となっている。これに対して、加振方法に復帰手段を付加した構造が特開平０９－１６７５４１（以下特許文献２として記載）として出願後、公開されている。 The method described in Patent Document 1 has a structure in which a vibration actuator is simply provided with respect to a method for exciting the touch panel. On the other hand, a structure in which a return means is added to the vibration method is disclosed as Japanese Patent Application Laid-Open No. 09-167541 (hereinafter referred to as Patent Document 2) after application.
　前記特許文献２に記載の構造では、前記特許文献１に記載されたタッチパネルに情報表示パネルを付加した入力方法を用いている。このような構造としたことで、特許文献２に記載の構造はタッチパネルに対する入力方法の幅を増やし、表示画面上に直接触れて入力することを可能としている。 The structure described in Patent Document 2 uses an input method in which an information display panel is added to the touch panel described in Patent Document 1. By adopting such a structure, the structure described in Patent Document 2 increases the width of the input method for the touch panel and enables direct input by touching the display screen.
　上記効果に加えて、特許文献２に記載の構造では入力に対する応答として、タッチパネル自体を水平方向に振動させる際に、復帰手段を内蔵した駆動源を用いた構造としている。この為、タッチパネルへの入力を停止した際にタッチパネルを自動で初期位置に復帰させることを可能としている。 In addition to the above effects, the structure described in Patent Document 2 uses a drive source with a built-in return means when vibrating the touch panel itself in the horizontal direction as a response to the input. For this reason, when the input to the touch panel is stopped, the touch panel can be automatically returned to the initial position.
　この為、特許文献１記載の構造に代表される従来のタッチパネル入力に対する触感フィードバック機能を、タッチパネル本体の厚みを増やすことなく追加することができると共に、表示画面と重ねた配置によってイメージガイドを省略した構造となっている。
For this reason, the tactile feedback function for the conventional touch panel input represented by the structure described in Patent Document 1 can be added without increasing the thickness of the touch panel body, and the image guide is omitted by overlapping the display screen. It has a structure.
特開平０４－１３７４１９JP 04-137419 特開平０９－１６７５４１JP 09-167541 A
　しかしながら、上記特許文献２に記載のタッチパネルはその構造上、タッチパネルに対する入力の検出手段とタッチパネル上での触感による出力手段とを別個に設ける必要があった。
　これは、特許文献２に記載のタッチパネル構造が基本的に従来のタッチパネル構造の振動方向を変えた物に留まっている為で、制御方法に関しては従来のタッチパネルと同様、別個に設けた入出力系統を使用しなければならないという課題を有している。また、復帰部を設けた事により、連続して入力を行う際に、入力時のデータに対して復帰動作中の入力がノイズとなってしまうと言う課題も有している。 However, because of the structure of the touch panel described in Patent Document 2, it is necessary to separately provide a means for detecting input to the touch panel and a means for outputting the touch on the touch panel.
This is because the touch panel structure described in Patent Document 2 basically remains the same with the vibration direction of the conventional touch panel structure changed, and the input / output system provided separately for the control method is the same as the conventional touch panel. Have the problem of having to use. In addition, since the return unit is provided, there is a problem that when performing continuous input, the input during the return operation becomes noise with respect to the data at the time of input.
　このような課題を解決するべく、本願は入出力系統を単一とすることが可能で、上記従来のものと同様の効果を得ることが出来るタッチパネルを提供することを目的としている。 In order to solve such a problem, the present application aims to provide a touch panel that can have a single input / output system and can obtain the same effect as the conventional one.
　前記目的のため、請求項１記載の発明では、圧電素子を駆動源とし、梃子を連結させた複合梃子型の変位拡大機構を、検出兼駆動源としてタッチパネル側面に設けた構造としている。この為、圧電素子を用いたタッチパネルの水平方向に於ける移動量の検出と、圧電素子の変位を前記変位拡大機構によって拡大したタッチパネル水平方向への変位出力とを、単一の部品で行うことが可能となる。 For this purpose, the invention according to claim 1 has a structure in which a composite insulator-type displacement expansion mechanism in which a piezoelectric element is used as a drive source and an insulator is connected is provided on the side of the touch panel as a detection and drive source. For this reason, the detection of the amount of movement in the horizontal direction of the touch panel using the piezoelectric element and the displacement output in the horizontal direction of the touch panel in which the displacement of the piezoelectric element is expanded by the displacement expansion mechanism are performed with a single component. Is possible.
　また、タッチパネルとタッチパネル取付筐体とを分けて振動させる為、前記取付筐体に別途入力手段を設けた構造であっても、振動出力に関わらず操作を行うことが可能となる。また、タッチパネルへの入力時に於いても、タッチパネルが変位拡大機構を介して取り付けられている為、接触による入力を圧電素子に対する変位として容易に検知することができる。 In addition, since the touch panel and the touch panel mounting casing are vibrated separately, even if the mounting casing has a separate input means, the operation can be performed regardless of the vibration output. Further, even when inputting to the touch panel, since the touch panel is attached via the displacement magnifying mechanism, the input due to the contact can be easily detected as the displacement with respect to the piezoelectric element.
　加えて、本発明に記載の構造ではタッチパネルが標準で有する入力機能も併せて使用することが可能となる為、タッチパネル本体への接触とタッチパネル本体の移動とを入力操作に併用する事で、多彩な入力機能を付加することができる。 In addition, since the input function that the touch panel has as a standard function can be used in the structure described in the present invention, it is possible to combine touch input with the touch panel and movement of the touch panel for input operations. Can be added.
　また、請求項２に記載の発明では、前記タッチパネルを変位拡大機構とサスペンションとで挟んだ支持構造を特徴としている。この為、入出力時に於いてタッチパネルの安定支持が可能になると共に、タッチパネル水平方向の移動を入力に用いる際でも、変位拡大機構を介した圧電素子への入力を安定して行うことができる。加えて、上記支持構造を用いることでパネル全体を水平方向に動かす構造となり、振動発生時に於いて、パネル上のどの位置でも同じ振動を感知することが可能となる。 Further, the invention according to claim 2 is characterized by a support structure in which the touch panel is sandwiched between a displacement magnifying mechanism and a suspension. For this reason, the touch panel can be stably supported at the time of input / output, and even when the horizontal movement of the touch panel is used for input, the input to the piezoelectric element via the displacement magnifying mechanism can be stably performed. In addition, by using the above support structure, the entire panel is moved in the horizontal direction, and the same vibration can be sensed at any position on the panel when the vibration is generated.
　また、請求項３に記載の発明では上述した変位拡大機構を少なくとも２カ所に設けた構造を用いている。この為、タッチパネル上での平面的な入力と押圧方向の入力とを別個に検出することが出来ると共に、出力軸を増やした事によって振動方向の自由度増加という効果をも得ることが出来る。また、タッチパネルへの入力時に於いても、検出を複数とすることでタッチパネルの取付筐体に対する水平方向の変位の他に傾きといった値を入力値として使用することが出来る為、使用者のタッチパネルを用いた入力の幅を増やし、より簡略化された入力手段を付加することができる。 Further, the invention according to claim 3 uses a structure in which the displacement magnifying mechanism described above is provided in at least two places. For this reason, the planar input on the touch panel and the input in the pressing direction can be detected separately, and the effect of increasing the degree of freedom in the vibration direction can be obtained by increasing the output shaft. In addition, even when inputting to the touch panel, by using multiple detections, it is possible to use values such as tilt in addition to horizontal displacement with respect to the mounting housing of the touch panel as input values. The width of the input used can be increased and more simplified input means can be added.
　また、請求項４に記載の発明では、前記変位拡大機構の駆動信号に進行波を用いる方法を提示している。この為、入力した進行波に従ってタッチパネルが使用者に対して方向性を付加した触感を提供することを可能としている。 Further, the invention according to claim 4 presents a method of using a traveling wave as a drive signal for the displacement magnifying mechanism. Therefore, the touch panel can provide a tactile sensation with added directionality to the user in accordance with the input traveling wave.
　以上述べたように、本発明に記載の構造を用いたタッチパネルは、タッチパネル表面に設けた導電性フィルムによる検出とは別に、タッチパネル自体の移動による入力とを備えることとなり、タッチパネルを用いた使用者の入力手段を広げ、より高い操作性を提供することが可能となる。
As described above, the touch panel using the structure described in the present invention is provided with input by movement of the touch panel itself in addition to detection by the conductive film provided on the surface of the touch panel. The input means can be expanded to provide higher operability.
本発明の最良の実施形態に於いて用いるタッチパネルの全体斜視図Overall perspective view of a touch panel used in the best mode of the present invention 本発明の最良の実施形態に於いて用いる変位拡大機構の斜視図The perspective view of the displacement expansion mechanism used in the best embodiment of the present invention 本発明の最良の実施形態に於いて用いる搬送用入力信号とそれに伴う動作The input signal for conveyance used in the best mode of the present invention and the operation associated therewith
　以下に、図１～図３を用いて、本発明に於ける最良の実施形態を示す。 Hereinafter, the best embodiment of the present invention will be described with reference to FIGS.
　図１に本実施例に於いて用いるタッチパネル構造の斜視図を、図２に本実施例に於いて用いる変位拡大機構の斜視図をそれぞれ示す。 1 is a perspective view of a touch panel structure used in the present embodiment, and FIG. 2 is a perspective view of a displacement enlarging mechanism used in the present embodiment.
　図１及び図２から解るように、本実施例に於けるタッチパネルは、圧電素子１３を駆動源とする複合梃子型の変位拡大機構１をタッチパネル本体３の側面２カ所に設け、それぞれの面の対向側にサスペンション２を設けて挟んだ支持構造となっている。この為、水平方向に自由度を有する振動をタッチパネル本体３に対して与えることが出来ると共に、タッチパネルに対する水平方向の入力をタッチパネル本体３の移動によって検出することも可能となった。 As can be seen from FIGS. 1 and 2, the touch panel in this embodiment is provided with a composite insulator type displacement expansion mechanism 1 using the piezoelectric element 13 as a drive source at two positions on the side surface of the touch panel body 3. A support structure is provided in which the suspension 2 is provided on the opposite side. For this reason, vibration having a degree of freedom in the horizontal direction can be applied to the touch panel body 3, and horizontal input to the touch panel can be detected by movement of the touch panel body 3.
　加えて、前記変位拡大機構１は前述した圧電素子１３の変位を支持部１１と梃子部１２とで拡大し、梃子部１２の端部に設けたガイド１４によって動作を安定させており、アクチュエータ自体の小型化によってタッチパネル本体３の面積を広く設定することを可能としている。 In addition, the displacement enlarging mechanism 1 enlarges the displacement of the piezoelectric element 13 by the support portion 11 and the lever portion 12 and stabilizes the operation by the guide 14 provided at the end portion of the lever portion 12, and the actuator itself. Thus, the area of the touch panel body 3 can be set wide.
　更に、前記支持構造を用いたことで体感振動発生時に取付筐体４に対してタッチパネル本体３を独立して振動させることができた。 Furthermore, by using the support structure, the touch panel main body 3 can be vibrated independently with respect to the mounting housing 4 when experiencing vibrations.
　上記効果に加えて、本実施例に記載のタッチパネルではその構造上、水平方向の振動発生時にタッチパネル本体３上のどの位置に触れていても同じ振動を感じることができるという利点がある。この為、タッチパネル本体３上を押圧移動させるような連続したタッチパネルへの入力に対しても、随時安定した触感フィードバックを返すことが可能となった。 In addition to the above effects, the touch panel described in the present embodiment has an advantage that the same vibration can be felt regardless of the position on the touch panel body 3 when the horizontal vibration is generated. For this reason, it becomes possible to return stable tactile feedback at any time even for continuous input to the touch panel such as pressing and moving on the touch panel body 3.
　図３に本実施例に於いて変位拡大機構１の駆動信号に用いる進行波と、それによる変位拡大機構１の動作を示す。図３から解るように、本実施例に記載のタッチパネルでは鋸刃形状の入力信号を用いることで触感に対して指向性を持たせることを可能としている。より具体的には、移動する方向と逆方向にパネルを急速移動させ（図中Ａ参照）、移動する方向に戻す動作を低速で（図中Ｂ参照）行う事で、支持部１１を起点とした圧電素子１３の変位が梃子部１２を動かしてタッチパネル本体３を移動させる制御方法を用いている。このような制御方法を用いる事によって急速移動時（図中Ａ参照）の動作に比べて低速動作時（図中Ｂ参照）の動作の方が使用者に感知されやすくなり、使用者に対して低速動作時の方向に沿った触感を伝達することができる。 FIG. 3 shows the traveling wave used for the drive signal of the displacement magnifying mechanism 1 in this embodiment, and the operation of the displacement magnifying mechanism 1 resulting therefrom. As can be seen from FIG. 3, the touch panel described in the present embodiment can provide directivity to the tactile sensation by using a sawtooth input signal. More specifically, by rapidly moving the panel in the direction opposite to the moving direction (see A in the figure) and performing the operation of returning to the moving direction at a low speed (see B in the figure), the support portion 11 is set as the starting point. A control method is used in which the displacement of the piezoelectric element 13 moves the touch panel body 3 by moving the lever portion 12. By using such a control method, the operation during low-speed operation (see B in the figure) is more easily perceived by the user than the operation during rapid movement (see A in the figure). The tactile sensation along the direction during low-speed operation can be transmitted.
　また、進行波の方向を逆転することで触感の上記進行方向を反対にすることができる。この為、タッチパネルに対する変位拡大機構１の設置箇所と入力信号との組み合わせによって本実施例に示した構造に限定される事のない、用途に合わせた触感出力と構成に調整することが可能となった。 Also, the traveling direction can be reversed by reversing the traveling wave direction. For this reason, it becomes possible to adjust the tactile sensation output and configuration according to the application without being limited to the structure shown in the present embodiment by the combination of the installation location of the displacement enlarging mechanism 1 with respect to the touch panel and the input signal. It was.
　以上述べた効果に加えて、本実施例冒頭で述べた変位拡大機構１を用いたことで、上記述べたタッチパネル全体の構成を小さくまとめながら、タッチパネル本体３の振幅を大きく設定することができた。また、駆動源に圧電素子１３を用いた事で立ち上がり時間を短縮すると共に、入力側に必要な回路構成を昇圧のみとし、簡単な制御で幅広い触感出力と入力手段とを提供することができた。 In addition to the effects described above, by using the displacement magnifying mechanism 1 described at the beginning of the present embodiment, the amplitude of the touch panel body 3 can be set large while reducing the overall configuration of the touch panel described above. . In addition, the use of the piezoelectric element 13 as a drive source shortened the rise time, and the circuit configuration required on the input side was only boosted, and a wide tactile output and input means could be provided with simple control.
　また、前記変位拡大機構を関して前記タッチパネルへの入力を行う際に、タッチパネルに対する水平方向の入力を画面表示に反映させることも可能となるため、従来のタッチパネルスイッチのみで行う操作に加えて、より多彩な入力手段を付与することが可能となった。加えて、本実施例に於いて用いた変位拡大機構１は、支持部１１と梃子部１２とを一体成形によって構成しており、振動出力等の連続した付加に対しても高い耐久性を維持することが可能となった。 In addition, when performing input to the touch panel with respect to the displacement enlarging mechanism, it is also possible to reflect the horizontal input to the touch panel on the screen display, so in addition to the operation performed only with the conventional touch panel switch, It became possible to give more various input means. In addition, the displacement magnifying mechanism 1 used in the present embodiment is configured by integrally forming the support portion 11 and the insulator portion 12, and maintains high durability against continuous addition of vibration output and the like. It became possible to do.
　以上述べたように、本実施例に記載の構造を用いることで、従来のタッチパネルが有していた効果に加えて、更なる操作性の向上が可能なタッチパネルを得ることができた。
As described above, by using the structure described in this embodiment, a touch panel capable of further improving operability in addition to the effects of the conventional touch panel can be obtained.
